Scrolltrigger Pin-spacer dynamic height

[PanosAx]

Hello, 

So i have a div that when you scroll into it it gets pinned and then the scrolling animation starts the animation is

tl.fromTo(".wrapper", {height: '554px', ease: "power4.inOut"}, {
height: '277px',
ease: "power4.inOut"
}, "start")

when the animation is done i have a huge gap from the pin-spacer.

after days of searching and trying multiple things i couldn't achieve dynamic pin spacer height.

 

ScrollTrigger.create({
pinnedContainer: "outer-div",
trigger: ".wrapper",
scrub: 1,
anticipatePin: 1,
pinType: "transform",
pinSpacing: true,
start: startPoint,
markers: true,
end: endPoint,
animation: tl,
toggleActions: "play none none reverse",

})

 

this is my scrolltrigger.

 

any help would be appreciated.

 

Thanks in advance

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo:

If you're using something like React/Next/Vue/Nuxt or some other framework, you may find StackBlitz easier to use. We have a series of collections with different templates for you to get started on these different frameworks: React/Next/Vue/Nuxt.

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.

Yeah, you're trying to animate the dimensions of the very same element that you're pinning which can't work. Pinning is complex and it is dependent on sizing and various other factors. I'd recommend just wrapping your page in a <div> and pin that instead:
